This is all nonsense. Within 1m, which is limited to any 40Gbps version, it is easier to use a 60GHz channel in the near field with a weak signal, but which will provide p2p exchange at speeds of 10Gbps over the radio channel. In practice, no one will bother with short and extremely unreliable TB3-5 cables at 40Gbps. This would make sense optically at a distance of up to 50-100m, but at 1m no one needs it. It is enough to buy an active regular cable for 5Gbps via USB-a.
Thunderbolt Share is intended to show why Thunderbolt 4 and 5 still have advantages over USB 4, because in future it will be possible to connect two computers directly to each other via a Thunderbolt cable in order to transfer data, share the display or use accessories with two computers.
